Application. filed May 14, 1906. Serial No 316,782.

To all whom; it may concern."

Be it known that 1, DEL oN G. lloiim', a citizen of the linitedfitates, residing at Albion, in the county of Orleans and State of New York, have invented. a new and useful 'Telepho'ne Attachment, of which the following is a specification.

This invention relates to telephone appliances; and it relates more particularly to an attachment for telephones whose function it is to $11 port the receiver at a point close to the ear a person using the telephone, so as to" do away with the ne sity of taking down the receiver and holding it to the ear during iii-conversation over the phone and. permitting the hands 'to be free, so as to write down ny matter being received, or for other purposes.

The objects of the invention are to provide a device of this character which ran be readily applied. to telephones in common use without reqi'iiring any alteration in the latter or skilled attendants to apply it, which is operatively connected with the receiver-hool so that the latter can be switched open or closed automatically by moving the receiver i supporting means out of or into position for conversation, and which is of simple and mexpcnsivc construction and very reliable and efilcient in operat on.

With these objects in view, and others, will appear as the nature of the invention is better under tood, the invention comprises the various novel features of construction and arrangement of parts, hereinafter fully described, and sctforth with particularity in the/claims appended hereto.

In the uccompzmyingdrawings. which illustrate one of the cn'ibodimeuts of which the invention is cupnble, Figure l is aside cle- Vution of the rriccivcr-liohlcr attachment applied to a telephone, the attachment. being shown in full lines in the position "the parts occupy when the telephone is in use and in dotted lines when the latter is not in use. Fig. 2 is a plan view thereof.

Corresponding parts in the several figures ara. imlicated throughout by similar charm-.

ter of reference. y I

Referring to the lrmvuigs, a telephone is shown of the standard wall type, thc same 1 comprising a baclr 1, a ringer-box 2,21 switch and battery containing cabinet 3, from which projects the usual receiver-hook 4, and the l transmitter 5 on the supportingnrm 6. As

present invention, it is merely shown for convenience in illustrating the attaclunent that coi'istitutes the invention.

The attachment comprises :1 base member or bracket 7, which is provided with suitablyspuced clips 8, which are adapted to fit over the transmitter-arm 6 and hold the attachment on the latter. The l'iracket 7 com prises a triangular frame 9, on one side of which the clips 8 are attached, and from the corner ofthc frame opposite to the side ha1ving the clips extends a laterally-projecting member 10 and a forwardly-projecting member 11, these members being continuations of the frame 7, which is'preferaliily made of strip metal of suitable dimensions to have the required rigidity and strength. On the forwanlly-extending part llof the bracket or frame 7 is pivoted for movement in a vertical plane an arm 12, which :itits outer end carries a cradle-shaped frame for holding the receiver. The arm i2 is pivoted on the bolt, y rivet, or the like 13 betweenv the plates 14, riveted on opposite sides and to the forward extension 11.

The cradle or frame for supporting the receiver, which latter is indicated in dotted lines at 15, comprises a laterally-projccting extension 16, bent from the metal strip con stituting the arm 12, and a diagonal brace 17, riveted at its ends to the arm and extension. Extending forwardly from the extension 16 are two U-shapcd holders 18, the free. ends of which are formed into hooks for engagement by the loops 1!) of the catches 20. Those holders are made of flexible pieces of metal looped at 2] so us to pass over and around thcrxtcnsiim l6 and one end of the I bruco l7. The loops also form means for anchoring' the catches 20. By means of this arr-angeluent tho r ceiver securely held on the outer end of the arm when the latter is in either its horizontal or vertical position, as shown in Fig. l.

(in the lateral extension 10 of the bracet 7' is mounted it lever or walking-beam 22, 1 pivoted at 2.; on an angle-plate 24, that is riveted to the outer end of the extension 10. [is shown in Fig. 12, the lever 22 is disposed in a vertical plane passing through the receiver book 4-, and from the inner end of the lever is suspended a weigh t 25 by means of the links HOBBY, ()I ALBION, NEW YORK, ASSIGNOR ()F Oi\'1t-HALF TO FRED L. FERRlS, ()F

the telephone per se forms no part of the 26, which weight is provided with an expandserves to hold the hook 1 down, so as to main tain the electric circuit open when the re ceiver-supporting urm 12 is in its inoperative position; but when the arm is moved forward to its operative position the v-xeight is adapted to be raised, so that the hook t can be lifted by its spring in the usual manner to close the clectric rircuit. The lever 22 is actuated by the receiYer-sopporting arm 12 indirectly through. the toggledinks 2S and 29, connected, respectively, to the arm 12 and the for "aid extension 1]. preferably in the form of a bell-crank lever, pivoted at 30, Fig. 1, and having a depending arm 31, that carries it laterally-extending iin er 32, that engages the free end ol'- the w king-beam or lever 22. The arm 12 as viewed from the side is formed in a com.- pound curve arranged with its outer end supported above the level oi the bracket 7. The arm 12 is SUPPUTlUd in'its extended position by means of a bifurcated portion of the link 28, which engages the arm 12 at the point 33, Fig. 1, thereby burning a stop that prevents the togglcdinks lr'd'in straightening completely it will he noted that the lever 22 abuts on the rear bottom edge oi the angle-plate 24, as indicated at 34, so that this lever, acting in conjunction with the arm 3] and linger 32, serves to support the receiverwarrying :n'm .Ifl. When the arm 12 is in its upright position, as shown by dotted lines in Fig. l, the upper end of the link 20 rests against the front upper edge ol" the lateral extension 10 at the point 35. It will be noted that when the parts are in this pos tion the weight oi. the rcccivcr-cerryir1g arm and that of the receiver acts on one side oi the pivot-point or fulcrum 13 ot the drill, so that the arm will positively ren'min in raised position al'ter once having been so placed.

011 the front side of the extension 10, as shown in Fig. i is an angle member or brace which receives the bolt 30, that passes 'therethrough and successively through the -bell-crank lever 29, the long plate 24, and forward extension 11, this bolt serv'ii'ig as the fulcrum for the bell-crank lever.

When it is desired to answer a call or send a telephonemessage, the person will first pull down the receiver-carrying arm from its ver tical to its horizontal position, thus bringing the receiver in close proximity to the ear while the speaker is in position in front of the transmitter. By this movement ofthe arm the finger 32 of the bell-crank lever 29 is low ered and moves thereby the beam 22, so that its rear end is raised to permit the circuit to be closed by the usuel receiver-hook 4. The arm remains in extended position during the conversation without any effort on the part of the speaker; When the conversation is The link 29 is emcee over, the arm is n'ioved back to its upright position, the some movement causing the finger 32 to be raised so that the walking-beam can be tilted under the influence of the weight stood that the apparatus shown is merely illustrative and that various changes in the arrangement of the parts and the minor 1 features of construction may be resorted to without sacrificing any of the advantages of the invention.
